Corn is a warm-season annual that is best planted after the soil temperature reaches 60Â°F, usually two or three weeks after the last frost in spring. Corn planted in cold, wet soil is unlikely to germinate. Corn grows best in air temperatures from 60Â° to 95Â°F.Corn can take from 60 to 100 days to reach harvest depending upon variety and the amount of heat during the growing season.orn seed germinates in 10 to 14 days at 75Â°F, but the rate of germination may reach only 75 percent. Start corn indoors 2 to 3 weeks before the last frost in spring for transplanting 2 to 3 weeks after the last frost. If your season is long enough, plant successive crops every two to three weeks.
